CLOTH-PRESSINGV MACHlNlL- SPECIFICATION forming part of Letters Patent No. 387,287, dated August 7, '1888.

Application filed September 4, 1886. Serial No. 212,702. (No model.)

To] all whom it may concern.-

Be it known thatl, DAVID GESSNER, of Worcester, county of WVorcester, State of Massachusetts, have invented a new and useful Improvement in Cloth-Pressing Machines, of which the following is a specification.

The object of this invention is to provide means whereby cloth may be treated with moisture after it has received a pressing and while it is still under pressure, so that as the moisture is introduced the fibers of the cloth are in a pressed condition and are held in such condition. This process is carried out by combining with pressing-surfacesa steamer or other moisteniug apparatus in such a way that the moisture is applied to the cloth under the conditions stated. The arrangement of these parts may be varied to a great extent; but I will first describe the apparatus which I prefcr to employ, and then point out some of the modifications of which it is susceptible.

Figure l of the drawings is an e'levation'of the machine taken from the side at which the cloth enters, the bed-plates being in position to press. Fig. 2 is a section taken through the line at w of Fig. 1, looking toward the right. Fig. 3 is a section through thelineyy, Fig.1, looking toward the left, excepting here the parts are shown in position with the bedplates thrown back. Fig. 4 is a detail cross- .section of the main cylinder, its bedplates and steamer attached to the right-hand bed plate. Fig. 5 is an enlarged view ofport-ions of the-same thing. Figs. 6 and-7 are the same as Figs. 4 and 5, excepting that here the steamer is attached to the-lefthand bed'plate. Fig. 8 shows the steamer of Fig. 7, with the cover removed and viewed in the direction o arrow av. cover in place and viewed in the (lllIBCtlOll Of arrow y. Fig. 10 shows the same from the direction of arrow 2, with the cylinderre moved. Figs. It to 17, inclusive, are some modifications of which the pressing-surfaces and moisteniug apparatus are. susceptible, which will. be more particularly referred to hereinafter.

' I will refer first to the apparatus shown -in Figs. 1 to 10, inclusive.

(1 is the main cylinder.

a is a second cylinder.

connection with a.

bb are bed-plates. b is a bed-plate in Fig. 9 shows the same with the- G is a steamer, which is fully shown in detail in Figs. 5 and 7. This steamer is com posed of a trough, c, which is secured to the edge of one of the bed-plates by bolts. The side of this steamer next to the cylinder is so formed as to continue the curve of the bedplate, and thus is in effect a prolongation of the pressing-surface of the bedplate. It will be observed that the pressing-surfaces thus extend fronithe perforations for the steamer in the direction from which the cloth is fed, so that the pressure upon the cloth commences before it is moistened. Thus the bed-plate to which the steamer is attached is prolonged end of the steamer from which steam is admitted.

f is a series of perforations or a slot for'med through the side of the steamer next'the' cylinder and through which the steam passes onto the cloth when held under pressure by the face of the cylinder and the steamer. Sometimes it may be desirable to have more than one series of perforations, as shown at Fig. 10, to make the flow of steam practically continuous, and thus prevent any streaking.

g is a deflector, placed between the pipe 6 and the perforationsfito-throw back any water which will find an outlet by the pipe h.

The cylinders a and a andthe bed-plates I),

b, and b are all hollow, so as to be heated by,

steam. The steamenters thecylinders and escapes therefromtlirough hollow journals, as shown at q q, and enters and escapes fromthe bed-plates, as shown at q q q j, iuconnection with the bed-plates b and b, respectively.

The cylinder a will be covered a felt jacket, a and asteamer, G", of ordinary construction, will be located below the cylinder, so as to throw vapor onto thejacket.

The bearingsot the cylinders a and a. are mounted inthe frame of the machine, as shown.

The mechanism employed for sustaining and,

operating the various bed-plates is such that be about vertical.

all of them may be moved to or from their respective cylinders simultaneously and by one movement of the hand. The bed-platesband b are swung by pivots at the bottoms of the suspension-rods j, which rods in turn are pivoted to ears j, projecting from the frameof the machine, as shown. These ears project out, so that when the bed-plates are pressing the suspension-rods will be inclined toward each other, as shown in Fig. 2; but when the bed plates are back from the cylinder the rods will Thus the weight of the bedplat'es will assist in throwing them back from the cylinder. The bed-plate b" is pivoted to a sliding bearing-maintained in vertical guideways in the frame, as shown at j".

k k k are the three arms of a lever which is fulcrumed concentric with the cylinder a. These arms are'respectively connected with the bed-plates b, b, and b' by the rods -l, l, and 1. Each of these rods, as well as the rods j, is provided with means for adj ustment lengthwise, consisting of opposite screw-threads formed on the ends of each rod, so that by turning the rod its available length will be shortened or lengthened, as required. The points of attachment of the rods Z Z l are all about equidistant from the fulcrum of the le= ver. The arm k is longer than the others, and to its extremity is secured a rod, *1, piv-' oted at'its lower end to the rod 2, which has on its ends levers 2,t'hat are pivoted to the machine at 3 to another rod,.as shown. A handle, 4, is connected with the lever 2, so that when it is desired to move the bed-plates the position of the rods 1 and levers 2 is moved from the position of Fig. 2 to the position of Fig. 3, or vice versa'. This mechanism enables the operator to move the bed-plates to and from the cylinders and far enough away from the cylinders for all practical purposes. It will be observed'that by reason of the connection of all the bed-plates to a common lever.

the weight of bed-plates b and 6 tends to counterbalance the weight of b.

It remains to provide means for applying pressure to the bed-plates when in position to press. is a lever pivoted to the frame at 6. 7 is a hook, which connects the lever 5 with the rod 2, to which rod land lever 2 are pivoted. Thus, when the parts are as shown in Fig. 2, downward pressure on the lever 5 is communicated 'to red 1, and thence is converted'into pressure by the bed-plates against the cylinders. This downward pressure on lever 5 is produced by the weight Sand is intensified by the interposition of the lever 9, pivoted to the frame at 10 andconnected with 5 by the link 11.

It now remains togprovide for the ready connecting and disconnecting of the weighting mechanism with the rod 1., 12 is a shaft, which is turned by the handle 13 on the outside of the frame. On this shaft is fixed the bell-crank lever-14, to one arm of which are 7 connected the links 15 and 16, and to the other arm the link 17. A lever, 18, as shown, is fastenedto a rod and pivoted to the frame, and one of its arms is pivoted to 17 while its other arm bears upward against the lever 9 and may be made to operate easily by a friction-roller attached at this point, if desired. A lever,19, as shown, is fastened to a rodpiv oted to the frame, and one arm thereof is pivoted to the link 16, while on the other arm is formed a hook, 20, arranged to engage with a projection on the hub of hook 7, as shown. On the side of hook 20 a projection is made to extend under lever 5, as shown. There is a slotted connection between 11 and 15; also between 14 and 16. The connection between 15 and 11 is made by passing the end of 5 into a mortise in 11, so that the connection can be "row, Fig.2, by the handle outside of the frame,

thefirst result will be to move bell crank lever 18, so as to slightly lift lever 9 and relieve lever 5 from the pressure of weight 8. This,by reason of the slotted connection, will take place beforethe links 11 or '16 are affected; but as soon as lever 14 has moved a short distance the link 11 will be disengaged from lever 5, as shown in Fig. 3, and the projection of hook 20 will reach under lever 5, so as to ease upon the grip which hook 7 has upon rod 2, whereupon the hook 20 will throw the hook 7 out of engagement with 2. At the same time the projection on hook 20 will press on the under side of lever 5 and hold it up'..

IIC

cylinders by' the gear-wheels 22 23 24 25 26, so

that the circumferential speed of both cylinders is the same. The gear-wheel 26 is constructed to slide on the shaft of cylinder a, so that it may be thrown into gear with 25 or with a gear-wheel, 27, which is provided with any known arrangement suitable for shifting its bearings, whereby it may be thrown into or out of gear with.25. This may be done by the sliding bearing 0' and the worm-gear o for moving the same, Fig. 2. Thus, by driving 26 directly from 25, or by the intervention of 27, the rotation of cylinder amay be reversed. The 010th enters at 28 and follows the course shown in the drawings. It will be pressed .by the bed-plate b. Then it will be held 'under pressure and at the same time treated with vapor between the steamer (l and the cylinder a.

'Then it will'be pressed by the bed-plate 6.

undergoing pressure by the bed=plate b the the cloth while under pressure.

cloth will be held in contact with the jacket, which has carried up the vapor received from steamer G, and this vapor is communicated to I I advise that the pressure exerted by the bed-plate b be of less intensity than that of the other bed-pl ates. After leaving the cylinder a the cloth may follow the course shown in full line, Fig. 2,0r the courseshown in broken line. In one case the cylinder a would be revolved in one direction, and in the other casein the opposite direction, and in the latter case the cloth would be moistened by thejacket on the same side as by the steamer C; but in the former case the cloth would be successively moistened on opposite sides. It is obvious that the bed plates 1; and b may be also used for'p'lain pressing simply while the introduction of moisture takes place between a and I) only. It is equally obvious that the cylinder at, bed-plate b, and steamer C may be omitted from the machine-and the remaining partsused without them; or the steamer C may be omitted,- and also one of the bed-plates b b, &c.

. has also arranged to bear against'it a felt apron which runs on the rollers m, n, and 0.

Instead of having steamer 0 arranged as described, it may be arranged as shown in Fig. 11, where it is placed in the middle of the bedplate. In this construction the face of the bed-plate forms a trough, d, within which fits the trough-shaped exterior of the steamcm which is extended into the metallic facing a of the bed-plate. This facing will be of unoxidizable metal. Within the steamer is the perforated pipe 6, located beperforations in the walls of the cylinder onto the cloth while under pressure by the bedplate. The cylinder may in this case be sustained on its exterior and be driven by ag'ear, 9. (Shown in Fig. 14:.) Another modification is shown in '15, 16, and 17. Here the cylinder a is provided with a bed-plate, b, and

Figs. 16and 17 show the arrangement of frame for supporting these rollers. It consists of three armsjointed upon acentral shaft, 10, and each arm provided with one of the rollers at its extremity. The bearings of the roll m are provided with any means of adjustment, so that it may be adjusted away from the shaftp and the belt drawn tightly. This adjustment may be effected by means of aset-screw, m, and slot m,between each bearing of the roller m and the arm supporting the same, as shown inFig. 16. 7

Any water formed passesv By having the frame arranged so that the rolls a and 0 press the apron against the cylinder and drawing the apron tight, a pressure is exerted between the apron and the'cylinder. A steamer is arranged,as at c, by which the apron is impregnated with vapor, so that while the cloth is under pressure between the apron and cylinder it will be treated with this vapor. At the same time it will be noticed that the steamer is arranged so as to deposit its moisture on the face of the apron which comes next the cloth, so that just sutficient moisture maybe supplied without completely saturating the apron, as would be necessary if the steamer was place on the oppositeside plate be made to press the apron upon the cloth, as indicated in dotted lines, Fig. 15, or if the rollers n and 0 be enlarged so'that the effect of their pressure will be increased.

It will be seen that in all cases when the steamer is attached to the heated bed-plates the steamer will be kept hot by the contact with the hot bed-plates, so that there is little or no danger of water forming inside of the steamer; and it is urderstood that thestcaxn will be turned off automatically from the supply-pipe of the steamer when the feed of the machine stops or at any time when the bedplates are relieved from pressure and required to be taken away from the cylinder, as showri'. Such an ar'rangementis described in my application,Seri al No. 195,943, filed March 20, 1886, and is not separately claimed herein.-

The perforations for the steam or moisture may be either in form of holes,in one or more rows, or inthe shape of slots, either being the equivalent of the other,aud it will be noticed that such perforations of the steamer are inclined toward the direction in which the cloth travels,so that the cloth in traveling over such perforations will not be abraded by the edges thereof, and thus, too, be moistened in a more effioient manner than would be the caseif the perforations ran in a vertical line to the path of the cloth.

It will be understood that, without departing from my invention in some cases,thie pressure upon the cloth while being moistened will be less intense than the other pressure, and may be so light insome cases as to be in the ICC IIO

nature rather of a contiuement,which I intend to include by the use of the term pressure.

I have made the process of treating the cloth herein described the subject of another application, .No. 212,703, and therefore make no claim to the same hereiin A certain combination shown in the machine described in this application has been made the subject of claim in an application filed by pressingsurface; a second pressing-surface opposite to the first; a steamer provided with a pressing-surface, which is also opposite to the first, and means whereby both 'the second pressing surface and the steamer are pressed against the cloth in opposition to the first pressing-surface, the second pressing-surface being arranged in advancev of the steamer,

whereby the cloth is pressed between dry surfaces and then pressed with the presence of steam or moisture, substantially as described.

The constructor of the machine described in this application may find the modifications shown in Figs. 11, 12, 13, 14, 15,16,- and 17 to be useful; but, excepting as the machine when containing the same may come within the scope of general claims,I do not wish inthis application to lay claim to the specific subjectmatter therein shown.

In an application filed by me December 27, 1887, No. 258,997, the specific modification shown in Fig. 14 herein is included; and I I therefore make no claim herein for the special features of this modification in contradistinction to the other arrangements shown.

In an application filed December 27, 1887, Serial No. 258,998, the specific modification shown in Figs. 15, 16, and 17 herein are included; and I therefore do not make any claims herein to the specific features shown in said modification in contradistinction to the other arrangements shown.

In anapplication filed by me April 16, 1888, Serial N o. 270, 825, I have shown and described certain features which are shown and described herein; but to the extent that they are claimed accessible from the end of the machine, and
